Fire Safety for Thatch

Reduce the risk and increase your Peace of Mind


Do thatched property fires occur more than those with conventional roofs or is it just people's perception?  Statistically, homes with thatched roofs are no more likely to catch fire than those with conventional roofs, however if they do the results are often rapid and spectacular.  It seems worse, mainly because thatched fires in unprotected properties usually causes severe damage and therefore receives maximum publicity.

The risk of thatch fires in old and new properties can be greatly reduced by taking sensible precautions and by utilising new specialist products to reduce the risk.

This guidance is goodwill advice and is not mandatory.  It applies to all types of properties and thatch but if alterations to listed buildings are proposed then reference should always be made to the Conservation Officer of the Local Authority for the area where the premises is sited.
